HOT-WATER HEATER.

SPECIFICATION forming' part of Letters Patent N0. 769,682, dated September 6, 1904-..

Application tiled March 21,1904.

Virginia,have made certain new and useful Im- A provements in Hot-Tater Heaters, of which the following is a specification.

My invention is an improvement in hotwater heaters; and it consists in certain novel constructions and combinations of parts, as

will be hereinafter described and claimed.

In the drawings, Figure I is a vertical longitudinal section of a heater embodying my invention. Fig. 2 is a cross-sectional view on about line 2 2 of Fig. I. Fig. 3 is a detail vertical section on about line 3 3 of Fig. Q.

In the construction shown my heater is formed with the ash-pit A, the tire-box B, and the smoke-arch C. The lire-box B is arranged above the grate D and includes the corner-posts or stand-pipes E, the rear connecting-pipes F, the side connecting-pipes G, and the front connecting-pipes H, extending between their respective stand-pipes E, as shown in Figs. l and Q. The stand-pipes may be of suitable dimensions in cross-section and are provided with projecting' bosses e, having the tapered sockets e' leading to their interiors and in which the tapered ends /i of the connecting'- pipes H tit and are drawn tightly by the tierods I, which latter extend through suitable ones of the connecting-tubes, thence through their respective stand-pipes, and receive at their ends the nuts J, which turn up against soft-metal packing K, so a tight joint may be secured between the connecting-pipes and the stand-pipes and the basket or tire-box formed by the stand-pipes and the connecting-pipes may be held securely in place as desired.

The ash-pit A has a door A' provided with a sliding' damper A2, and the tirebox has a doorway BQ controlled by the door B2, supported in the frame B3, the latter being held in place by the hooked rods B", secured at their outer ends, preferably by threading them to receive the nuts, as shown, to the doorframe B:s and provided at their inner ends with hooks engaging the connecting-pipes H immediately above and below the doorway Serial No. 199,163. (No model.)

B. This construction is simple,easily applied, and enables me to readily secure the doorframe in place so it can be removed whenever necessary.

At their upper ends the stand-pipes E are provided with tapered openings rfi, and above the tire-box I support the hollow crown-sheet or dolne IC, which is provided in its under side with openings coinciding with the openings 2 in the upper ends of the stand-pipes. The Lipper ends of the stand-pipes and the hollow crown or dome K are connected by the tubes L, tapered at their upper and lower ends to lit in the coincident openings and as will be understood from Figs. l and of the drawings, ings E and E2 heilig' provided on the stand-pipes and crown or dome and connected by the bolts L', which may be tightened in order to press the connectingtubes L lirml y into connection with the stand-pipes and the hollow crown or dome, as best shown in Fig. 3 of the drawings.

The hollow crown K is preferably provided on its under side with a number of depending tubes K2, which hang directly over the tire in the fire-box, so that the coldest water in the crown-sheet or dome will fall in such tubes and become heated to a high degree before it is discharged from the crown or dome to the pipes leading to the radiators. In Fig. 2 I show the pipes M leading to the lower ends of the stand-pipes for conducting the cool water returned from the radiators into the lower ends of the stand-pipes, pipes being' connected at K with the crown or dome to carry the hot water off to the radiators of the system with which the heater is employed. It may be desirable to employ separate pipes connecting' each radiator directly with the heater, and for this purpose it will be noticed that I have provided several connections at K for the outgoing hot wat-er and several connections M for the incoming cold water. It will be noticed that the several stand-pipes and connectingtubes are directlyin contact with the lire and are also so disposed that the heat may circulate around them in order to extract heat units to raise the temperature of the water. 'It will further be noticed that the connectingpipes being level or horizontal the water will circulate by variation in temperature, the water passing from one corner-post or standpipe into pipes at one end and thence to the opposite stand-pipe, thence to the pipe above, and so on, rising gradually as it increases in temperature until it is discharged into the crown or dome, whence it may be taken to the radiators. In the operation or circulation of the Water the feed-Water entering from the pipes M at the lower ends of the verse direction toward the ends of such connecting-pipe, thence up to the next connecting-pipe, and so on, the cooler water flowing from the ends of the connecting-pipes inwardly toward the middles thereof, thence up and in the reverse direction toward the ends of such pipe, the heat meanwhile circulating entirely around the connecting-pipe, as will be understood from the drawings. It will be noticed that the crown or domev is exposed on its under side to the heat from the fire-box, and the heat and products of combustion will circulate around the said crown at the sides thereof, passing to the smoke-box C and thence out the uptake C, which latter may be controlled by a damper C2, as shown.

A door C3 is provided leading to the smokebox, so the same may be cleaned out whenever required.

The heater may be bricked in, as illustrated in the drawings. v

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The improvement in heaters herein described, comprising the corner stand-pipes, provided in their upper ends with tapered openings, the connecting-tubes extending between the said stand-pipes, the hollow crown or dorne above the stand-pipes, and provided in its under side with taperedopenings coinciding with those in the upper ends of the stand-pipes, the tubes tapered at their opposite ends and fitting in the coincident openings of the crown-sheet or dome and the standpipes, bolts connecting thedome and standpipes, the door-frame, the hooked rods connected with the door-frame and engaging with the front connecting-pipes, and thetie-rods extending through the connecting-pipes and the opposite stand-pipes and secured substantially as and for the purposes set forth.

2. The combination of the stand-pipes, connecting-pipes between the opposite standpipes and ranging in vertical tiers, the hollow crown or dome above the stand-pipes, connecting-tubes between the upper ends of the standpipes and the hollow crown or dome, and connections between the stand-pipes and the dome for drawing the same together, substantially as set forth.

3. The combination of stand-pipes provided at their upper ends with .lugs and having tapered openings in said ends, the dome above the stand-pipes and provided with lugs and with tapered openings in coincidence with those in the stand-pipes, the connecting-tubes tapered at their ends and fitting at such ends in the coincident openings in the dome and stand-pipes, bolts connecting' the lugs of the stand-pipes with those of the dome, the connectingpipes between the opposite standpipes, and the tie-rods passing through said connecting-pipes and stand-pipes and secured, substantially as set forth.

4. A heater substantially as described, comforth.
